The game is controlled exclusively with the space bar and the up and down arrow keys. With the first you accelerate and keep ahead of the police, while the others help you dodge traffic. If you crash into other vehicles, your car will deteriorate and the police will catch you.
Speedrun is a simple game where you only have one goal: to drive as far as possible to keep the police from catching you. The only negative point about its simple gameplay is that you can't compete on any online leader boards.
